More Info — Algae Control & Pool Algaecide

Proper circulation and balanced pool water chemistry is the best way to prevent algae growth, but even carefully maintained swimming pools may experience algae once in a while. It is important to use an effective algae treatment as soon as an algae bloom appears in your pool. It’s also a good idea to take proactive measures to prevent algae from growing in your pool in the first place.

Algae spores typically enter pool water from wind and storms. When conditions are right and your water isn’t properly balanced, you may find yourself with an algae bloom. Not only is it an eyesore, it can cause damage to pool surfaces and harbor disease-causing microorganisms. There are three types of algae commonly found in swimming pools: Green Algae, Yellow/Mustard Algae and Black Algae.
